|Realization of Current-mode Quadrature Oscillator Based on Third Order Technique|
This article presents a 3rd current-mode quadrature oscillator using current controlled current conveyor transconductance amplifier (CCCCTA) and operational transconductance amplifier (OTA) as active element as active elements. The proposed circuit is realized from a noninverting lossless integrator and an inverting second orderlow-pass filter. The oscillation condition and oscillation frequency can be electronically/orthogonally controlled via input bias currents...
